Perception

Spot, listen, search, and notice.

Perception is the one skill every living creature uses every waking moment. It covers spotting (visual detection), listening (auditory awareness), searching (deliberate investigation of an area), and noticing (passive, subconscious awareness of something wrong). In the verse, Perception is the difference between seeing the tripwire and being the headline. It opposes Stealth for biological observers and Deception for social lies. It is the ONLY skill that is a class skill for all nine archetypes -- every soldier, scholar, and scoundrel needs eyes and ears.

Notes

Special: Perception is a class skill for ALL nine archetypes (the only one in the skill list). Passive Perception is checked automatically against Stealth and Deception. Combat awareness uses Initiative DEX adjustment, not Perception.

Untrained: May make passive Perception checks (no action required) and active Perception checks (standard action) but without trained bonuses. No penalty for untrained use; simply lower total.
